Embodiment Construction

[0026] Below in conjunction with accompanying drawing and embodiment, further elaborate the present invention.

[0027] The orientation mentioned in this manual refers to the direction of the vibration system of the speaker unit, and the orientation refers to the direction of the magnetic circuit system of the speaker unit. The inner side of the housing mentioned in this specification refers to the side of the housing located in the inner cavity of the module, and the outer side of the housing refers to the side of the housing located outside the inner cavity of the module.

[0028] Such as figure 1 , figure 2 , image 3 with Figure 4 Commonly shown, a loudspeaker module is installed inside electronic terminals such as Pad, and has a rectangular structure, including a shell, and the shell is composed of a first shell 10, a second shell 20 and a third shell 30 that are sequentially combined. In the configuration, the space enclosed by the first casing 10, the second casin...

Abstract

The invention discloses a loudspeaker module, and relates to the technical field of electroacoustic products. The loudspeaker module is arranged in an electronic terminal, and comprises a shell, a vibrating system and a magnetic circuit system are contained in the shell, the magnetic circuit system comprises a basin stand fixed to the shell, a magnet and a washer are fixed in the basin stand in sequence, and rear sound output holes are formed in the positions, corresponding to the side walls of the basin stand, of the shell, and communicated with an inner cavity of the module and an inner cavity of the electronic terminal. Chamfered planes are arranged at the upper ends of the side walls, corresponding to the rear sound output holes, of the basin stand, and arranged on the sides, close to the rear sound output holes, of the side walls of the basin stand. According to the loudspeaker module, the technical problem that a loudspeaker module in the prior art is large in size and low in frequency, and distortion occurs easily is solved, the loudspeaker module guarantees acoustic performance, meanwhile, the size is reduced to the minimum, the need for the light, thin and small electronic terminal is met, stability is high, and the service life is long.

Description

technical field [0001] The invention relates to the technical field of electroacoustic products, in particular to a loudspeaker module. Background technique [0002] The loudspeaker module is an important acoustic component in a portable electronic terminal, which is used to complete the conversion between electrical signals and sound signals, and is an energy conversion device. The loudspeaker module usually includes a casing, in which a speaker unit is accommodated, and the speaker unit includes a vibration system and a magnetic circuit system. The inner cavity of the existing speaker module is divided into two cavities by the vibration system. One is the front sound cavity located in front of the vibration system. The sound is transmitted out; the other is the rear sound chamber located behind the vibration system, the rear sound chamber is a closed cavity, which is used to improve the low-frequency performance of the speaker module and prevent acoustic short circuit. I...
